To all whom it may concern.' n

Be it known that I, CHARLES WV. SHEvLIn, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Container', of which the following 1s a specification..

My invention relates to contalners made of paper or tissue which is infused or 1mpregnated with a suitable substance to render it impervious to air or moisture or liquids so that the containermay be elther used for containing liquids, or for contaming other substances free from the actlon of exterior air or moisture or liquids.

The use of parafiin as a substance for treating paper to render it imperviouspto water is Well known. In order, however, to secure the best results the substance of the tissue must be thoroughly homogeneously' infused or impregnated with Ithe material',

and not merely coated with it, as a more or' less thorough coating not having the bonding action of the tissue is liable to. checking or'cracking which, of course, spolls its 1ntegrity. It is known, also, that When paper is impregnated with paraffin 1t is weakened, and even the harder varieties of parain have a more or less greasy character which` tends to collect dust and will interfere with the labeling of the container with either printing directly upon it, or by means of a label designed to be secured thereto. It may or may not be known, but, nevertheless is a fact, that an article cannot be successfully both glued and impregnated with paraffin, for the reason that glue requires for its successful action both in its own substance andin the substance to which itis applied a certain amount of moisture, while the action of paraiin is to drive out all the moisture. It is known that a. paper impregnated withr paraflincannotbe successfully glued, and when an article which has been previously glued is impregnated with parain the glue is caused to let go.

In View of the above physical conditions my present invention has for its object the provision of a container which will embody all the advantages to be derived from an impregnated liner, together with an unimpregnated outer casing.

Another, and very essential object, is the provision of both the outer casing and liner in one integral strip, thus simplifying the construction.

I attain the above objects by the structure illustrated in the accompanying drawings, in which- Figure l is a central section through a completed container; Fig. 2 is a perspective view of the outer casing or first lap of the container, temporarily held in shape by staples, the liner or remaining impregnated strip being shown spirallly'wound and partially withdrawn and Fig. 3 is a plan view of the container blank.l

Similar reference numerals designate similar parts throughout the several views.

Reference snumeral 4 designates the entire continuous blank from which the walls of the body -0f my container are made,

of the blank which forms the outer casing', and which is not impregnated; and 6 desigblank, whichb is liomogeneously impregnated Vwi'th'a, ymaterial suitable for the use towhich the package is to be put. After the portion 6 of the blank 4 has been impregnated, the blank is then rolled up with the portion 5 on the outside. This port-ion or outer lap, is held temporarily in position by suitable staples 7. The lining 6, or remaining por- 'tion of the blank, due to its expansiveness resulting from coiling, will tend to expand and contact with the inner surface of the outer wall 5. This tendency, however, should be supplementedI by a suitable former or mandrel, the action of which will secure a uniform and perfect contact between the layers forming the liner 6 and the outer casing 5. When paraffin is used as the impregnating material the container is then heated, and the outer and inner casings are caused, by the known properties of parain, to adhere together, forming a solidwal'l, the inner portion being homogeneously impregnated while the outer portion remains only slightly coated upon its inner surface, and unimpregnated, thus rendering the package walls water-proof, while at the same time, the outside walls thereof will retain their original strength and be suitable for any purpose for which a container of ordinary paper may be used. Interiorly opening beads 8 are turned in the said walls, a suitable distance from the top and from the bottom, said beads forming interior grooves for the two end members 9 and 10,

the other end 9 is ring s aped to provide an while the numeral 5 designates the portion "natosthef,liner',or the other .portion of the the bottom end 10 bein a solid disk, while annular shoulder or flange 11 so that av disk 12 may be placed thereon to form a top closure or cover for the package. '.Ihe ends of the body walls are then turned lnwardly as at 13, thus formin internal shoulders abuttin the ends 9 an 10.

aving described my inventlon what I claim a's new' and desire to secure by Letters Patent, is v 1. 'A method for forming containers comprising the thorougha'nd homogeneous infusion and impregnation of a strip of fibrous material with a cementitious moisture resistin material, the formation of a c lindrica shell, theV insertion of said in sed stri within said shell, andthe pressing of sai infused strip so that it will contact with and adhere to the walls of said shell.

2. A method for forming containers comprising the thoroughA and homogeneous infusion andimpregnation of a strip of fibrous material with wax, the formation of a cylindrical shell, the insertion of Vsaid waxed strip within said shell, and the pressing and heating thereof so that it (will contact with .and adhere to the walls of said shell.

3.v A method for forming containers comthe thorough and homogeneous infusion and impregnation `o'f-aportion of a stri of fibrous material with' a cementitious moisture resistl material, the formation of a cylindrical shel from the unimpregnated ortion of said strip, the insertion of the impregnated ortion of said strip within said shell, an the pressin thereof so that it will contact with and ad ere to the walls of said shell.

4. A method for forming containers comprl'lsing the thorough and homogeneous in- 'on and impregnation of a portion of a strip of fibrous material with wax, the for- .matlon of a cylindrical shell from the unimpregnated portion of said strip, the insertion of thewaxed ortion of said strip within said shell, and t e pressing and heatin thereof so that it will contact with and adere to the walls ofsaid shell.

In testimony whereof I aix my signature in the presence of two witnesses.
